AI-assisted cheating is the single biggest threat to technical hiring assessments right now. With tools like ChatGPT capable of solving basic to intermediate coding problems in seconds, recruiters face a difficult question: how do you know a candidate actually solved the test themselves?
HackerEarth's Smart Browser addresses this directly. It is a purpose-built desktop application that locks down the testing environment, preventing candidates from accessing AI tools, external resources, or any form of assistance during an assessment.
The results are measurable. Internal data shows that assessments conducted through the Smart Browser see significantly lower solvability rates, meaning the candidates who pass are genuinely skilled rather than AI-assisted.
This article breaks down exactly what the Smart Browser does, the data behind its impact on assessment integrity, how it compares to standard browser-based proctoring, when to use it versus allowing AI, and the technical requirements for getting started. Whether you are running high-volume campus hiring or screening senior developers, this guide will help you decide if the Smart Browser fits your assessment strategy.
What Is the Smart Browser and Why Does It Matter?
The Smart Browser is a dedicated desktop application that candidates download and install before taking a HackerEarth assessment. Unlike standard browser-based tests (where candidates take assessments in Chrome, Firefox, or Safari), the Smart Browser creates a controlled environment that restricts access to everything outside the test window.
Think of it as the difference between an open-book exam and a supervised, closed-room test. Browser-based proctoring can detect tab switches and flag suspicious behaviour, but determined candidates can still work around it. The Smart Browser removes those workarounds entirely by operating as a standalone application with system-level restrictions.
This distinction matters because the rise of large language models has fundamentally changed the cheating landscape. A 2024 study published in the British Journal of Educational Technology found that AI-assisted cheating in online assessments increased by over 60% between 2022 and 2024. Standard browser-based proctoring was not designed to counter this level of sophistication.
For recruiters and hiring managers evaluating remote proctoring for online assessments, the Smart Browser represents the most rigorous option available within the HackerEarth platform.
Core Features and Restrictions
The Smart Browser prevents the following candidate actions during an assessment:
- Screen sharing the test window with any application or service
- Keeping other applications open during the test (all non-essential apps are blocked)
- Resizing the test window to view content behind it
- Using multiple monitors (only the primary display is active)
- Taking screenshots or recording the test window
- Running the test inside a virtual machine (VM detection is built in)
- Accessing browser developer tools
- Viewing OS notifications that might contain copied content
The application also restricts specific keystrokes and key combinations:
- All function keys and combos (F1, F5 + Alt, etc.)
- Alt + Tab (application switching)
- Ctrl + Alt + Delete (task manager access)
- Ctrl + C and Ctrl + V (copy-paste)
- OS superkeys (Windows Key, Mac Command Key) and their combinations
These restrictions collectively ensure that candidates cannot access ChatGPT, code repositories, documentation, or any external resource during the test.
What the Smart Browser Data Reveals About Assessment Integrity
One year after launching the Smart Browser, HackerEarth analysed the impact of this feature on assessment outcomes. The central metric was solvability, which measures how many candidates successfully solve each question type.
A well-designed assessment should have a solvability rate between 10% and 20%, depending on difficulty level and candidate pool size. Too high, and the assessment is not differentiating effectively. Too low, and the test may be unreasonably difficult.
Here is what the data showed.
Scenario A: Assessments Without Smart Browser
When candidates took assessments in a standard browser environment (with basic proctoring but no Smart Browser restrictions), solvability was higher across all question types. The standard proctoring still presented a challenge due to HackerEarth's rich question library, but candidates had opportunities to use external tools, including AI assistants.
Even with these solvability rates, the assessments were not trivially easy. However, the risk remained: genuine candidates who solved problems independently competed on an uneven playing field with those using ChatGPT or similar tools.
Scenario B: Assessments With Smart Browser
After implementing the Smart Browser on the same assessments, solvability decreased significantly across every question type. The controlled environment ensured that only candidates who could solve problems using their own knowledge and reasoning passed the test.
The Solvability Impact
The overall decrease in solvability when Smart Browser was enabled confirms a critical insight: a meaningful percentage of candidates in unproctored environments were relying on external assistance.
This does not mean every candidate in Scenario A was cheating. But the data demonstrates that stricter proctoring separates candidates who can solve problems independently from those who cannot. For recruiting teams, this translates to a higher-quality shortlist where every candidate on the list has demonstrated verified skills.
The bottom line: the Smart Browser does not make tests harder. It makes the results more trustworthy.
Why Proctored Assessments Matter More in the Age of AI
The assessment integrity challenge is not theoretical. Large language models are improving at an accelerating pace, and their ability to solve coding problems grows with each model release.
Consider the progression:
- GPT-3.5 (2022): Could solve basic coding challenges and common algorithm problems
- GPT-4 (2023): Handled intermediate and some advanced coding tasks, including data structures and system design questions
- GPT-4o and Claude 3.5 (2024-2025): Consistently solve complex, multi-step coding problems with high accuracy
For take-home coding assessments sent without proctoring, AI can now handle a significant portion of the question types recruiters rely on to evaluate candidates. This puts hiring teams in a position where unproctored test results may not reflect actual candidate ability.
The problem extends beyond individual cheating. When AI-assisted candidates advance to interviews and cannot replicate their assessment performance, your engineering team wastes hours on interviews that should never have happened. That is time pulled directly from product work.
Robust proctoring through tools like the Smart Browser directly addresses this by ensuring that the assessment stage of your hiring funnel produces reliable signals. When combined with technical interview platforms that evaluate candidates in real-time, you create a multi-layered process where AI-assisted cheating has no viable entry point.
Smart Browser vs. Standard Browser-Based Proctoring
Not all proctoring is equal. Understanding the differences helps you choose the right level of security for each assessment.
Standard browser-based proctoring works well for lower-stakes assessments or situations where you want a lighter candidate experience. It detects suspicious behaviour and flags it for review.
The Smart Browser is designed for higher-stakes assessments where you need certainty, not just flags. When the cost of a bad hire is significant (senior engineering roles, for example), the trade-off of requiring an app download is well worth the integrity it provides.
For teams looking to improve the candidate experience while still maintaining assessment integrity, a tiered approach works well: use browser-based proctoring for initial screening rounds and reserve the Smart Browser for final technical assessments.
When to Use the Smart Browser (and When to Allow AI)
This is where the decision becomes strategic rather than technical. The Smart Browser gives you the ability to create a fully locked-down assessment environment. But that does not mean you should use it for every test.
Option 1: Block AI Access Entirely
Use the Smart Browser when the primary goal is evaluating a candidate's core programming skills, specifically:
- Syntax familiarity and language proficiency
- Problem-solving ability without external assistance
- Algorithm design and optimisation under constraints
- Code efficiency and clean coding practices
This approach is ideal for high-volume hiring where you need to filter large candidate pools efficiently. Campus recruitment drives, associate-level engineering roles, and standardised skill assessments are strong use cases.
The Smart Browser ensures that every candidate who passes the assessment did so on their own ability. Your shortlist becomes a reliable signal for the next stage.
Option 2: Allow AI to Expand the Assessment Scope
For senior or specialised roles, consider allowing AI tool access during assessments. Many experienced developers already use AI assistants as part of their daily workflow. Evaluating how a candidate uses AI (prompt engineering, code review, solution refinement) can reveal higher-order skills that a locked-down test cannot measure.
Think of it the way writing professionals use spell checkers. The tool does not replace skill; it augments it. For roles where AI collaboration is part of the job, testing candidates without AI access may actually give you a less accurate picture of their real-world capabilities.
In these scenarios, focus the assessment on:
- System design and architectural thinking
- Code review, debugging, and optimisation of AI-generated code
- Problem decomposition and communication
- Creativity and novel approaches to ambiguous problems
The key is matching your proctoring level to what you are trying to measure. The Smart Browser is a tool, not a mandate.
Technical Requirements and Getting Started
System Requirements
The Smart Browser is a lightweight desktop application. Candidates need to download and install it before the assessment begins. The supported environments include:
- Windows: Windows 10 and Windows 11
- macOS: Version 13.5 (Ventura) and above
- Linux: Ubuntu 20.04, 22.04, and 24.04
The application requires a stable internet connection throughout the assessment. Specific hardware requirements (RAM, disk space) are minimal, as the application primarily functions as a controlled browser environment rather than a resource-intensive program.
Rolling Out Smart Browser to Candidates
Communication matters when introducing a proctored environment. Candidates who are surprised by a desktop application download are more likely to drop off or have a negative experience. Best practices include:
- Notify candidates in advance. Include Smart Browser requirements in the assessment invitation email with clear download instructions.
- Provide a test run. Allow candidates to install and verify the application before the scheduled assessment window.
- Offer technical support. Link to troubleshooting guides and provide a support contact for installation issues.
- Explain the purpose. Frame the Smart Browser as a fairness measure. Candidates who are confident in their skills generally appreciate a level playing field.
Setting up the Smart Browser on the recruiter side is straightforward. Within the HackerEarth assessment configuration, toggle the Smart Browser proctoring option when creating or editing a test. The platform handles the rest, including generating candidate-facing instructions.
For teams exploring AI-powered interview tools alongside proctored assessments, the Smart Browser integrates within the broader HackerEarth ecosystem. You can use it for the assessment stage and pair it with AI or human-led interviews for subsequent evaluation rounds.
Security, Privacy, and Candidate Data
Assessment proctoring involves monitoring candidate behaviour, which raises legitimate privacy questions. Transparency about what the Smart Browser does (and does not do) builds trust with candidates and ensures compliance with data protection standards.
What the Smart Browser monitors:
- Application and window activity on the candidate's device during the test
- Keystroke restrictions (blocking specific key combinations, not logging keystrokes)
- Attempts to access restricted functionality (screenshots, screen sharing, virtual machines)
What the Smart Browser does not do:
- It does not access the candidate's webcam or microphone (unless webcam proctoring is separately enabled)
- It does not log personal files, browsing history, or data outside the test session
- It does not remain active or collect data after the assessment is completed
HackerEarth follows industry-standard security practices including data encryption in transit and at rest. For enterprise customers with specific compliance requirements (SOC 2, GDPR), the platform offers detailed documentation on data handling practices.
If your organisation operates under strict data governance policies, review HackerEarth's security documentation or contact the support team to confirm alignment with your requirements.
Make Your Assessments Trustworthy
Assessment integrity is not a nice-to-have. It is the foundation that every subsequent hiring decision rests on. If your assessments can be gamed with AI tools, your shortlists are unreliable, your engineering team wastes time on mismatched interviews, and your cost-per-hire rises.
The Smart Browser gives you a proven, data-backed way to restore trust in your assessment results. The solvability data speaks clearly: when candidates cannot rely on external help, only the genuinely skilled ones advance.
